zo claims.

This invention relates to apparatus, especially useful in a paperwinding machine, to eject rolls of paper from the machine and to feed aspare y winder shaft to the machine for the next winding operation.

More particularly the invention relates to apparatus forautomaticallyvopening upthe bearing caps of a web winding machine, forautomatically ejecting wound rolls from the machine, and forautomatically supplying a new winder shaft to the bearing caps of themachine.

The apparatus of this invention will hereinafter be specificallydescribed in combination with a paper rewinder and slitter machine withwhich it is particularly useful. However, it should be understood thatthe roll-ejecting and winder moves a spare winder shaft out of a pocketin the machine to feed the spare shaft to the bearing caps. The bearingcaps are then closed and the machine is ready for the next windingoperation.

The rewinder machine can receive the full width paper web from the reelof a paper machine and will first trim the deckle edges of this web.

The vertically movable slitter assembly of the rewinder machine isbrought down on top of the roll being wound 'on the winder shaft after afew turns of trimmed paper have been wound on the shaft. Pos/itivelydriven slitter disks on this assembly cut through these turns of the webto completely sever the web into a plurality of strips or ribbons. Theslitter disks then ride on top of the rolls being wound to continuetoslit the incoming web. As a result a plurality of rolls will be formedsimultaneously on the same winder shaft but the threading of individualribbons of paper on the winder shaft is avoided since the slittingoperation` does not start until the full width web has been wound forseveral turns on the shaft. A

As a result of this invention the manual handling of rolls and windershafts into and out of a rewinder machine is eliminated and one electionoperation of the handling apparatus takes care of a plurality ofindividual rolls.

It is, then, an object of this invention to provide a paper windingmachine capable of simultaneously winding a plurality of independentrolls and capable of simultaneously ejecting all of the Wound rolls.

A further object of the invention is to provide roll-handling apparatuswhich automaticallyv opens the winder shaft bearing caps of a. rewindermachine, ejects the wound rolls from the machine and feeds a sparewinder shaft to the machine.

Another object of the invention is to provide improved roll-handlingapparatus for paper rewinders which positively feeds a spare windershaft into the bearing caps of the rewinder after ejecting the woundroll or rolls from the rewinder.

A further object of the invention is to provide roll handling apparatusfor paper winder machines which sweeps in one direction to release thewinder shaft bearing caps of the machine, then sweeps in the oppositedirection to discharge the Wound roll or rolls from the machine and nextsweeps in `a reverse direction to feed the spare winder shaft into themachine.

Other and further objects of the invention will be apparent to thoseskilled in the art from the following detailed description of theannexed sheets of drawings which, by Way of preferred example,illustrate one embodiment of the invention.

On the drawings:

Figure 8 is an enlarged fragmentary cross-sec- I, tional view with partsin elevation taken along `,.theline VIII-VII of Figure 3.

Figure 9 is a wiring diagram illustrating the automatic control of theejector andsparewinder shaft feed mechanism. As shown in the drawings:In Figure l the referenceA character I designates `generallya Winder orrewinder machine adapted for receiving a web of paper W directly fromthe unwinding stand (not shown) of a paper making machine. The machineII) includes a frame structure II rotatably supporting a bottom slittershaft I2 adapted to receive the web W thereover. Trimmers such as T areprovided for cutting off the deckle edges of the web W. The web W isdirected from the top of the shaft I2 beneath the first Winder underdrum I3. A second Winder under drum I4 is rotatably mounted in closelyspaced horizontal relation from the drum I3. The two under drums I3 andI4 provide a nip I5 therebetween for receiving therein a Winder shaft Son which a roll R is wound from the web W. 'Ihe shaft S is carried atits ends in split bearing caps I6. The bearing caps I6 are mounted onthe ends of arms such as I1 carried on carriages such as I8. Thecarriages I8 are slidable in vertical grooves I9 provided by standardssuch as 20 in the frame structure. The arms I1 can thus ride verticallyin the grooves I9 toward and away from the under drums I3 and I4 andwill ride upwardly as the roll R builds up in diameter.

The bearing caps I6, prior to the winding operation, can be set at anydesired level in the nip I5 between the under drums I3 and I4 by meansof chains such as 2|- which have the ends thereof connected to thecarriages such as I8 at 2Ia and 2 Ib respectively.

The chains such as 2| are trained around lower sprockets such as 22 andupper sprockets such as 23. The upper sprockets 23 are keyed on a shaft24 carrying, at one end thereof, another sprocket 25 operated through achain 26 from a. hand wheel 21 on the side of the machine. A ratchet 28rotatable with the hand wheel 21 cooperates With a pawl 29 to hold. thechain 26 in fixed position for preventing unauthorized lowerlng of thecarriages I8. 'Ihe pawl 29 is adapted to be tripped when desired by afoot pedal 30 connected to the pawl through a linkage 3|.

The carriages such as I8 can raise freely in the grooved tracks such asI9, since the chain 2l will rotate the sprockets 22 and 23 therebyrotating the sprocket 25 to move the chain 25 and hand wheel 21. Theratchet will merely click past the pawl 29 during this raising movement.However, the carriages I8 cannot be lowered unless the pawl is trippedby the foot pedal 30.

The bearing caps I6 will therefore raise away from the under drums I3and I4 as the roll R builds up in diameter but When the roll R lsejected from the bearing caps the bearing caps 'will not fall downunless they are manually lowered by operation of the hand wheel and footpedal.

to 4'counterweighis such as 31.

ably mounted on the top. oj the frame stricture II. The other ends ofthe chains 35 are secured The counterweights 31 have rollers 38 thereonriding on Ways such as 39 of the frame I I.

The sprockets 36 can be secured to a single shaft 49 which carries aratchet 4I acted on by a spring-pressed pawl 42 and adapted to bemanually disengaged bya trip handle 43. The slitter roll assembly 32 canthus be manually raised in the grooves 4I 9 away from the roll R and thecounterweights 31 facilitate this manual raising of the assembly. Thepawl 42, when allowed to engage the ratchet 4I, will hold the assemblyin its raised position until it is tripped by the operating handle 43.

The frame standards 20 carry rack bars such as 44. The rack bars 44 arein toothed engagement with spur gears such as 45 carried by the endframes 33 in bearing housings such as 46. In order to impart resistanceto the rotation of the spur gears 45 friction clutches can be usedthereby resisting the raising and lowering of the assembly.

Motors such as 41 drive belts such as 48 which rotate the slitter diskshaft 49. The slitter disk shaft contains a plurality of disk-typeslitters such as 50 adapted to cut the web W being wound into a roll andalso adapted to cut through the A rider Sutter assembly 32 includingsubf frames such as 33 at the ends thereof having groove-engagingcarriages such as 34 riding in the grooves I9 of the frame standards'20is provided above the bearing cap carriages I8. The slitter assembly isthus mounted in the main frame II of the Winder machine to ride up anddown above the roll R being wound by the machine.

Sprocket chains such as 35 are attached at first few turns of paper onthe Winder shaft S for completely severing the web into independentribbons and thereby make possible the production of a plurality of rollsat the same time on a single Winder shaft. The Winder shaft can begrooved to permit entry of the edges of the cutter thereby insuring thecutting of the first few turns of paper on the shaft.

As best shown in Figures 2 and 3, the under drum I4 has axle portions 5Irotatably mounted in bearing housings 52 carried by the main frames II.Straps 53 are rotatably mounted on these axle portions 5I between thedrum I4 and the bearing housings. The straps 53 have gear segments 54thereon meshing with spur gears 55 on a drive shaft 56 which extendsacross the machine and is rotatably mounted in bearing housings 51. Amotor M is coupled to the shaft 56 to drive the same.

A discharge platform 58 is carried by the main frame and extends acrossthe top of the under drum I4 in spaced relation from the winding nipbetween the drums. This platform has pockets 59 adapted to receive thespare Winder shaft (not shown). Roll supporting ribs 60 extend from theplatform 58 to guide the rolls of paper out of the machine.

Slots 58a are formed in the platform 58 and receive the spare Windershaft feeder arms `6I therein. The feeder arms 6I are pivotally mountedas at 6Ia to the platform structure and, when in inoperative position,lie flush with the top of the platform or just under the top of theplatform.

The other ends of the arms 6I are pivotally connected as at 6Ib to linkrods 62. The link rods 62 are pivoted on crank arms 63 carried by ashaft 64 which is driven through a sprocket and chain drive 65 from theshaft 56. In extremely wide machines, 'a pair of shafts 64 and a pair ofsprocket chain drives 65 may be used.

In order to impart resistance to the rotation of the shaft 64 and toprevent coasting of the shaft. a friction clutch assembly 66 best shownin Figure 8 is provided. As therein shown, the platform structure 58carries a cup-shaped housing l61 through which the shaft 64 is freelyrotatable. A pair of clutch elements 68 and 69 are keyed to the shaft 64by means of a key 10. 'I'hese clutch elements carry friction clutchdisks 1| on their opposed faces.

The housing 61 has an internally toothed ring 12 bolted to the open endthereofas by bolts such as 12m. A plate 13 is disposed between thefriction disks 1| and has external teeth meshed with the internal teethof the ring 12. The plate 13 thus oats in the ring 12 in geared orsplined relation thereto.

A strap 14 is disposed around the shaft 64 in spaced relation from thehousing and abuts acoil spring which acts on the clutch element 69. Thestrap 14 can be adjusted on the shaft 64 to vary the spring compressionas desired.

With the spring 15 urging the clutch element 69 against the plate 13 theplate 13 will be squeezed between the friction disks 1|, and since it isgeared or splined to the ring 12, it willimpart resistance to therotation of the shaft 64. In the event that a plurality of shafts 64 areused, a plurality of friction clutch assemblies 66 would be used, onefor each shaft.

85a to engage the spare Winder shaft and push the same over the drum I4into the open bearing caps.

The abutment faces 84a and 85a of the arms 84 and 85 are maintainedinspaced opposed relation and the arm 85 is adjustably mounted on the gearsegment 54, through bolts 86 which extend through slots 81 in the arm85.

As best shown in Figures 4 to 6, the chain and sprocket drive such asthe drive 65 between the shaft 64 and the shaft 56 described above inconnection with Figures 2 and 3 includes a Referring again to Figures 2and 3, it will be noted that one of the bearing housings 52 for theunder drum I4 has a trough-like track |16 mounted on the top thereof.This track is open ended and extends from a point adjacent the bearingcap I6 for the winder shaft S. The Winder shaft S and spare Winder shaftSS are preferably equipped with thrust bearings B on one end portionthereof for thrusting against the sides of the bearing cap I6. One ofthese thrust bearings B is adapted to ride in the track |16 for guidingthe spare Winder shaft into the bearing cap. As shown in Figure 1, thetrack |16 slopes downwardly at its inner end below the tops of the rollsI3 and I4.

As best shown in Figures 4 to 7, the bearing caps |6 each are composedof a bottom member |6a. fixedly carried by the arm I1 and a top member|6b pivoted to the arm |1 as at |6c. The top member I6b has a dog ortooth |6d projecting from the free end thereof adapted to be engaged bythe latching finger 16 of a latching device 11 which is pivoted to thelower cap portion |6a as at 18. The latching device 11 iscounterweighted as at 11a and a spring 19 may be interposed between thelatching member 11 and the arm portion |1 to further urge the latchingdevice for'moving the nger 'i6 into engagement with the tooth |6d.

A spring 80 is disposed around the pivot |6c for the bearing cap portion|6b and has the ends thereof acting respectively on a stop 8| on the arml1 and a. stop 82 on the bearing cap portion |61). The spring 88 is thuseffective in urging the cap |6b to the open position shown in Figures 5to 7. y

The straps 53 disposed around the axles 5| of the drum i4 each carry atripping pin 83 adapted toengage the latching device 11 to trip the nger16 off of the tooth |6d and permit the cap portion |6b to spring to openposition.

Each strap 53 also carries an ejector arm 84 having' an abutment face84a, adapted to engage the end portions of the winder sha-ft S formoving the same out of the bearing caps and out of the machine. Y

The gear segment 54 carries a spare Winder shaft pusher arm 85 having anabutmentfacc sprocket 65a, freely mounted on the shaft 64. A pawl 65h ispivotally mounted on the sprocket 65a and is spring urged by a spring65o also carried by thesprocket against a cam 65d keyed to the shaft 64.The cam 65d has a single tooth 65e adapted to be engaged by the pawl65h.

As explained above, the shaft 56 is driven by the motor M to drive thechain of the chain drive 65. This chain drives the sprocket 65a torotate the pawl 65h around the cam 65d until the pawl engages the tooth65e whereupon the shaft 64 will be driven. The motor M is a reversiblemotor as will be hereinafter fully described.

When the rolls such as R are completely wound by the under drums I3 andI4 as shown in Figure 4, the shaft 56 is driven by the motor M in acounter-clockwise direction. This will raise the gear segment 54 therebyswinging the straps 53 to move the pins 83 against the bearing caplatching devices 11 and release the latchF ing fingers 16 from the teeth|6d of the bearing caps. The bearing caps will then spring open.

During the latch tripping operation with the shaft 56 moving in acounter-clockwise direction the sprocket 65a will also be moved in acounterclockwise direction to move the pawl 65h against the tooth 65eand thereby driving the shaft 64 to position the crank arms 63 at thebottom of their strokes. The spare winder shaft feeding arms ,6| thushave the ends 6|b thereof moved below the pocket 59 for the spare windershaft SS. The spare Winder shaft SS is already positioned in thepocketfor the feeding operation.

The motor M is then reversed to drive the shaft 56 in a clockwisedirection. This will effect a lowering of the gear segments 54 and araising of the ejector arms 84 to position theirifaces 84a against theends of the Winder shaft S. Continued movement ofthe ejector arms willforce the Winder shaft S to carry the rolls R thereon over the top ofthe under drum |4 with one of the thrust bearings B on the shaft spacedabove the track |16. After the arms 84 have pushed the shaft S over thetop of the drum |4 the rolls R will roll downwardly over the platform 58across the pocket 59 and over the discharge arms 68.

During this clockwise movement of the shaft 56 the pawl 85h on thesprocket 65a has merely backed away from the tooth65e of the cam 65d andhas rotated around the cam so that the shaft 64 is not driven, as showninxFigure 5. As a result the feed arms 6| for the spare Winder shaftwill not be moved. l y

After the rolls R have rolled past the pocket 59 for the spare Windershaft SS the motor M is again reversed to again drive the shaft 56 inacounter-clockwise direction as indicated in Figure 6. shaft 58 willagain raise the segment gears 54 and will again move the pawl65b on thesprocket 65a against the tooth 05e on the cam 65d thereby driving theshaft 54 to raise the crank arms 63 thereon and move the links 02 toraise the arms 6I for lifting the spare winder shaft SS out of thepocket 59 and rolling the same over the platform 58 onto the drum I4. Bythe time the spare Winder shaft SS reaches the drum I4 the abutmentfaces 85a onthe feed arms 85 have been raised due to the raising of thegear segments 54 into pushing engagement with the spare winder shaft SSto move the same over the top of the drum I4. One of the thrust bearingsB and the spare Winder shaft is in position for the next windingoperation.

During the next winding operation, the shaft S can be retracted from therolls R wound thereon and deposited in the pocket 59. It thereuponbecomes a spare Winder shaft for the following winding operation.

The roll handling apparatusthus first moves in one direction to open thebearing caps, then moves in a. reverse direction to eject the woundrolls of paper from the under drum and next moves hack to feed in thespare winder shaft.

At the start of the winding operation the leading end of the web W istrained under the drum I3 and between the Winder shaft and the drum. Itis then tucked over the winder shaft between the shaft and the drum I4.Tuckers (not shown) can be used for the tucking operation. To facilitatethe tucking operation and to move the leading end of the web W from theroll I3 over the top of the Winder shaft. an air pipe 90 (Figure 2) canbe mounted across the top of the drum I3.

This air pipe can have nozzles 90a along its length to direct streams ofair under the web overlying the drum I3 thereby blowing the leading endof the web over the Winder shaft S so that the tuckers can engage theleading end and tuck the same between the shaft and the drum I4. If verylightweight paper is being directly wound `around a collapsible windershaft, it may be desirable to protect the first few turns of paperagainst tearing when the collapsible shaft is withdrawn by covering theshaft with a sheet of heavier paper. For this purpose a tray 9| as alsoshown in Figure 2 can be molmted above the drum I3 for holding sheets ofheavier liner paper. A sheet of liner paper can be laid over the drumsI3 and I4 and .over the leading end of the web W to be wound.

The windet shaft is then inserted on top of the liner paper and an airblast from the pipe 90 will then raise boththe leading end of the web Wand the liner sheet from the roll I3 to permit the tuckers to tuck bothsheets around the shaft.

The wiring diagram of Figure 9 illustrates the manner in which the motorM can be controlled through its reversing cycles for moving therollhandling apparatus as described above.

InA Figure 9 the reference numerals 95, 98 and 91 represent' 3-phasecurrent conductors to reversing switches RS1 and RSz. These conductorscommunicate through the switches with power lines 95a, 96a, and 91arespectively to the motor A M of the machine.

The switch RS1 is controlled by a contactor 38 including an operating orenergizing coil 98a.

The switch RS: is likewise controlled by a contactor 99 including anoperating coil 99a.

A control arm |00 is swingabiy mounted, for example, on a strap 53 ofthe machine so as to swing with the ejector arm 84. The control arm |00can obviously be mounted in any suitable position as long as it has thesame swinging movement'imparted thereto as is imparted to the ejectorarm or strap 53.

'I'his control arm |00 has a tipped end I00a for actuating limitswitches LS1, LSz and LSa. The limit switches LS1 and LS; havespring-biased toggle arms controlling a pair of contactors. In otherwords the limit switch LS1 includes a contactor C1 and a contactor C12while the limit switch LS: has a contactor C3 and a contactor Ca2.

The limit switch LSz has a single contactor C2. However the control armof this limit switch carries in pivotal relation thereto a dependinglatch IOI which is acted on by the arm I00a. This latch IOI, due to itspivotal mounting, eiects movement of the contactor Cz of the switch onlywhen the arm |00 is driven in a clockwise direction. When the arm movespast the switch in a counter-clockwise Vdirection the latch I0| ismerely tripped without in any Way moving the switch.

' A push-button P. B. is mounted in the circuit and, when thispush-button is manually depressed, it closes the circuit through thecontactor Crof the limit switch LSs and the contactor 98 to the coil99a. 'I'his coilis thus energized and raises the contactor 99 so as tothrow the reversing switch Rs2 across the 3-phase line in such a way asto drive the motor M in a direction for unlatching the bearing caps ofthe machine.

As the contactor 99 raises it closes, in addition to the reversingswitch RSz, a pair of contacts that by-pass the push-button so that themotor will continue to run even though the push-button Y switch RSz willthen drop to open position. However, when this occurs the contactor C32of the limit switch LS; closes the circuit through the contactor C12 ofthe limit switch LS1 and the contactor 99 of the reversing switch RS2 tothe coil .98a of the reversing switch RS1. The coil will thereupon movethe reversing switch RS1 to a position for throwing the motor across the3-phase line in such a way as to cause it to run in the eject directionas indicated. The contactor 98 at the same time closes its own holdingcircuit and the motor will continue to run until the arm gets back tothe limit switch LS1. As explained above, the arm in swinging back tothe limit switch LS1 wil1 not aiect the switch LSzv since it will merelytrip the latch IOI thereof.

When the arm trips the limit switch -LS1 the contactor C12 thereof opensthe holding circuit through the coil a and the reversing switch RS?.drops to open position. At the same time, however, the contactor C1closes the circuit through the contactor C3 of the limit switch LSx andthe contactor 98 of the reversing switch RS1 to the coll 93a of thereversing switch RSz thereby again moving the switch to its closedposition and again reversing the motor. The contacter 99 will againcomplete its holding circuit and the motor will continue to run in adirection for feeding in the spare Winder shaft until the arm end Iatrips position shown in solid lines to hold the limit than necessitatedIf desired, of course, the motor can be con-v trolled by manuallyoperated switches.` The Wiring diagram of Figure 9, however, permitsfull automatic operation of the motor.

It will, of course, be understood that various details of constructionmayLbe variedk through a Wide range Without departing from theprinciples of this invention and it is, therefore, not the purpose tolimit the patent granted hereon otherwise by the scope -of the appendedclaims.
